Definitions

  • the present invention relates to fireproof glazing.
  • the invention relates to glazings comprising one or more intumescent layers.
  • Fire protection glazing of this type must meet well-defined specifications, including standards such as European standards EN 1363-1 and 1364-1 for walls, or 1634-1 for doors and windows. These characteristics are of course aimed at the properties of fire resistance, but to these fundamental characteristics of the glazing in question must be added others which are fixed by the known modes of manufacture, or by the requirements of the users.
  • Intumescent layers in addition to their fire resistance properties must meet a series of requirements. They must especially be perfectly transparent, have no defects such as the presence of bubbles or a veil diffusing light. Such defects are inherent in the compounds constituting these layers and in the modes of preparation of these layers.
  • the usual mode of preparation of the hydrated alkali silicate layers comprises the formation of a solution of these compounds, the deposition on a glass sheet of a uniformly distributed quantity of this solution to constitute a film of the order of a few millimeters d thickness, then drying this film up to to form a transparent solid material.
  • These drying operations are the subject of delicate techniques and difficult to master perfectly.
  • obtaining a layer free of bubbles usually passes through prolonged drying. This drying is longer as the layer is thicker. In fact, the drying time increases much more than proportionally to the thickness. For this reason it is preferable not to increase too much the thickness of the intumescent layer or layers of these glazings.
  • the effectiveness of the layer depends directly on the thickness thereof.
  • a thickness of several millimeters is necessary. But experience shows that beyond 2 or 3mm thick, the drying time becomes industrially crippling. For these reasons, it is customary to distribute the intumescent material in several layers each of more limited thickness. These layers are separated by as many sheets of glass.
  • the fire-resistant glazings according to the invention are as indicated in claim 1. These glazings withstand some of the most severe fireproofing, namely combining sealing and insulation for very long periods of 90 minutes. (EI90) or even 120 minutes (EI120), and are in thicknesses respectively at most equal to 37 and 54mm.
  • the glazing In addition to the fire resistance properties, the glazing must also offer mechanical qualities for "normal" use conditions, ie out of fire exposure. These depend closely on the use that is made of them, but even for those that do not require very particular performances, a minimum is required, which very small glass thicknesses do not make it possible to satisfy.
  • two types of solutions have been proposed if the solution of using reinforced glasses is not used, since the latter do not offer the optical quality required.
  • the first solution is to modify the glasses used. An increase in the thickness makes it possible to improve the mechanical strength but has the counterpart of a greater total thickness. This tendency is all the less desirable as the need to reinforce the structures appears essentially for less fire-resistant glazings, and consequently which must be the least thick.
  • the inventors have made glazings of complex structure comprising alternating intumescent layers based on hydrated alkali silicates on the one hand, and glass sheets on the other hand.
  • the intumescent material layers of the glazings according to the invention do not have a thickness greater than 2.0 mm, and not less than 1.4 mm.
  • the thickness of the intumescent layers is between 1.5 and 1.8 mm.
  • the optical qualities are very difficult to obtain under conditions of preparation time, especially drying, industrially acceptable.
  • Less than 1.4mm the number of layers required, and consequently the number of glass sheets used in the composition of the final glazing, are disadvantageous from the point of view of the cost of these windows, and moreover, the thickness of the assembly does not meet the usual constraints.
  • the glazings according to the invention combine a number of glass sheets at least equal to that of the intumescent layers present in this glazing.
  • the structure has this particular, the two outer faces must necessarily be those of glass sheets, two intumescent layers are contiguous to each other. This arrangement is not contrary to the requirements indicated above with regard to the upper limit of the thicknesses that can be obtained by drying.
  • the assembly which leads to attaching two layers of intumescent material occurs in effect once the drying achieved.
  • the final product comprises an intumescent layer which is then double, and the thickness limits indicated above are also doubled for this layer formed by joining two previously dried layers.
  • the "double" layers can be up to 4mm thick.
  • the glazings according to the invention comprise at least two assemblies formed of two contiguous layers, and moreover as many sheets of interlayer material minus one that there are "double" layers. It is indeed possible to multiply the double layers, but this leads to then assemble sheets of glass by means of interlayer sheets of the type used for the traditional constitution of laminated glazing. These include polyvinylbutyral sheet or ethylene vinyl acetate.
  • the thickness of the glass sheets must remain within certain limits. In practice these sheets are not more than 4mm thick and preferably not more than 3.5mm. Preferably this thickness is not greater than 3.1mm.
  • the thickness of the glass sheets may be uniform. This procedure has the advantage of allowing the constitution of glazing by means of all identical elements. However, it is possible to assemble from different elements. For products that must remain relatively light, the presence of at least one sheet of glass of greater thickness can offer advantageous mechanical characteristics without causing an inadequate total thickness.
  • the glass sheets when the number of glass sheets is greater than that of the intumescent layers, in order to maintain the conditions relating to the total thickness of the glass it is necessary that the glass sheets, or at least those in number equal to that of the intumescent layers, are Thin well limited.
  • the number of glass sheets when the number of glass sheets is greater than that of the intumescent layers, at least a number equal to that of these layers has a thickness which is not greater than 2.5 mm. Preferably this thickness is not greater than 2.3 mm and advantageously not greater than 2.1 mm.
  • the thickness of a large number of glass sheets of the assembly is relatively limited, it is possible, while maintaining a total thickness suitable, to have at least one glass sheet thicker to stiffen and improve the strength of the assembly.
  • the thickness of this additional sheet is nevertheless limited so as not to increase the weight and the thickness of the assembly excessively. It is advantageously 5 mm and more, and preferably 6 mm and more. The thickness of this sheet does not normally exceed 10mm.
  • the additional sheet or sheets may be of the monolithic type. They may also be in the form of a laminate consisting of two sheets of glass traditionally joined by an interlayer sheet of a plastic material. For this purpose, a sheet of PVB (polyvinyl butyral) or EVA is usually used.
  • PVB polyvinyl butyral
  • EVA EVA
  • the use of a laminate gives the glass mechanical qualities well known.
  • laminated glasses is preferably reserved for implementations in which the plastic sheet is not likely to be too directly exposed to fire. It is therefore relatively complex structures, or structures in which the laminated panel is located asymmetrically on the side that is not likely to be exposed to fire.
  • a thicker monolithic sheet When a thicker monolithic sheet is part of the structure, its position is not as critical as for the laminate. However, it is preferably located on the side exposed to fire. Experience shows that even when subjected to thermal shock leading to its rupture, the protection of the underlying intumescent layer is better ensured.
  • the thermal inertia of this thicker sheet leads in particular to a more homogeneous distribution of the heat and consequently to a more uniform expansion of this layer, avoiding the premature tearing of the pieces of the broken sheet.
  • intumescent layers As in assemblies comprising an equal number of glass sheets and intumescent layers, it is possible to join several intumescent layers in structures comprising additional monolithic or laminated glass sheets.
  • the lamination may also relate to the glass sheets meeting the thickness criteria indicated above.
  • the glazings according to the invention advantageously consist of sheets of glass which, with the possible exception of the sheet, or so-called additional sheets, are all of the same thickness.
  • the intumescent layers associated with these glass sheets are advantageously of the same composition and of the same thickness.
  • modules comprising two, three or four identical glass sheets, each carrying a layer of alkali silicate previously dried, can be combined by the usual treatment techniques in this case. domain, basically a collage by steaming under pressure of these sheets to form modules.
  • These modules comprise a face constituted by a glass sheet, and a face having the intumescent layer.
  • These modules can then be associated with either a sheet constituting the second face of the glazing unit, or by means of a sheet (monolithic or laminated) to a module which may be different, but which is preferably identical. Under these conditions (assembly of two identical modules) the structure is symmetrical and the possibly different thickness of glass, or laminated glass, is in the middle of the structure.
  • the glass sheets used according to the invention are most usually made of conventional silico-soda-lime glass. They may optionally be replaced in whole or in part by glass sheets having improved mechanical and thermal characteristics. It may be in particular glass sheets having a lower coefficient of expansion, thus ensuring better resistance to deformation under the effect of heat. These are well known compositions, for example borosilicates. Glasses of this type advantageously have an expansion coefficient which is not greater than 7.5 ⁇ 10 -6 / ° C.
  • the sheets may also have undergone treatments, in particular of the chemical or thermal quenching type, to give them stresses favoring their mechanical strength.
  • the production of the glazings contemplated by the invention requires the formation of a solid and transparent hydrated alkali silicate layer from a solution which is gradually dried.
  • the formation of this layer and its drying are carried out directly on a glass sheet.
  • the basic element (a) as schematized in figure 1 comprises a glass sheet (1) on which there is a previously partially dried alkaline silicate layer (2).
  • the formation of glazing according to the invention involves the assembly of several basic elements (a), as shown in FIG. figure 2 .
  • the assembled structure comprises a succession of glass sheets (1) and layers of hydrated alkali silicate (2).
  • the number of basic elements is even higher than the fire resistance must be greater.
  • FIGS. Figures 3 and 4 show a glazing unit in which the last base element (a) is thus applied by its intumescent layer to the similar layer of the preceding element.
  • the structure thus constituted only of basic elements comprises as many sheets of glass as hydrated alkali silicate layer, but two of the latter are gathered forming of course a layer of greater thickness (3).
  • the glass sheet (4) of the last element here constituting the second external face of the glazing.
  • the bonding of the two intumescent layers, in addition to the thickness, is identifiable by the structure of these layers. Their mode of formation makes it possible to distinguish the surface exposed to drying from the remainder of the layer. The presence of two contiguous surfaces retains peculiarities in the heart of the layer formed of two elementary layers.
  • each module consists of three basic elements (a).
  • This type of assembly can give rise to very varied combinations likely to respond to different modes of use.
  • the glazings according to the invention apart from the basic elements (a), may also comprise other components.
  • the Figures 5 to 9 illustrate different glazings with additional elements.
  • the figure 5 shows an assembly of a series of elements (a) to which an additional glass sheet is associated to "cover" the last hydrated alkali silicate layer.
  • the last sheet is of the same thickness as that of the elements (a).
  • An identical structure can be obtained by assembling two modules themselves formed of several basic elements (a) by interposing between the two silicate layers of each of the two modules an additional glass sheet.
  • the use of relatively thin sheets and intumescent layers makes it possible to achieve even slightly thick glazing. Nevertheless, this choice leads to limiting the mechanical strength, in particular for the lightest structures.
  • the thickness gain optionally makes it possible to complete the assemblies formed of elements (a) of small thickness by a substantially thicker glass sheet, in particular to achieve improved mechanical properties.
  • the Figures 6 and 7 illustrate the constitution of glazings which comprise a glass sheet (6,7) thicker than that of the elements (a).
  • the thick sheet is centrally located between two modules each in the example comprising three elements (a).
  • the thicker sheet (7) constitutes an outer face of the glazing.
  • a thick sheet is intended to enhance the mechanical strength of the glazing outside of the fire exposure, to meet the various requirements that may be those of glazing in their "ordinary" use and particularly when they come into the composition of partition, door, etc.
  • plastic interleaves such as those used in laminated safety glazing.
  • the interleaves in question are well known to glassmakers. This is most usually PVB (polyvinyl butyral) or EVA sheets. These transparent products allow the breaking of the glass sheets to maintain the fragments in position thus avoiding the dangers caused by the possible fall of these fragments.
  • the sheet of organic material may further contain additives improving its fire resistance.
  • FIGs 8 and 9 illustrate two structures incorporating a plastic interlayer sheet (10).
  • the formation of these structures is similar to those represented in Figures 6 and 7 , the thick sheet (7) being replaced by a laminated glass (11) comprising the interlayer (10).
  • the presence of the interlayer has advantages in addition to those concerning the impact resistance.
  • the products in question constitute in particular a UV barrier which can lead to the aging of the intumescent layers. The aging of these layers can cause the appearance of a veil, or that of bubbles. UV protection is therefore particularly desirable for windows exposed to UV light such as façade glazing. In this case it is desirable to have the laminate on the side of the glazing most directly exposed to UV. Glazing of the type illustrated in the figure 9 is preferred to those in which the spacer sheet is in the core, as shown in FIG. figure 8 .
  • the leaves are of clear silico-soda-lime glass.
  • the intumescent layers consist of hydrated alkali silicate with an SiO 2 / Na 2 O molar ratio of 3.3.
  • the initial solution deposited on the sheets before drying further comprises 7% by weight of glycerine and 0.5% by weight of TMHA (tetramethylammonium hydroxide) and 65% of water.
  • the water content of the material is reduced to about 20%. Drying is achieved in a 24-hour cycle.
  • the sheets carrying the layers of hydrated alkali silicate are assembled by calendering or pre-bonding under vacuum, followed by steaming under pressure for 1 hour at 120 ° C.
  • the following glazings have been constituted.
